Data on Industrial Edge device is not persistent using example docker compose file

[stefschm]

Using the example docker compose configuration is working but the data is stored only not persistent in working memory. Could you please provide an example which enables persistent data storage?

myapp:
  environment:
    ADMIN_PASSWORD: *******
    DATABASE_ENDPOINT: 'jdbc:hsqldb:file:~/data/database/db:mem:mendix'
    MXRUNTIME_DatabaseType: HSQLDB
    MXRUNTIME_DatabaseJdbcUrl: 'jdbc:hsqldb:file:~/data/database/db:mem:mendix'
    IEM_CONFIG_PATH: /cfg-data
  image: 'sample_app:1.1'
  volumes:
    - './publish/:/publish/'
    - './cfg-data/:/cfg-data/'
  mem_limit: 1gb
  restart: unless-stopped
  ports:
